Something you need to know about Geotextile

Geotextile, also known as engineering fabric, is an engineering material produced by needle-punching technology with synthetic fibers such as polyester, polypropylene, spandex, ethylene, and even, in the shape of cloth, generally 4-6 meters wide and 50-100 meters long. The following are the places that should be noted when using geotextiles.

Geotextile laying process requirements.

1. Grass-roots inspection: check whether the grass-roots level is flat and solid, and if there are foreign objects, they should be handled properly.

2. Test laying: according to the site, determine the size of the geotextile, cut it and test lay it, the cut size should be accurate.

3. Check whether the width of the spreading is suitable, the lap should be flat and loose, and tight.

4. Positioning: Use a hot air gun to bond the lap part of two geotextiles, the spacing of the bonding point should be suitable.

5. The stitching line should be straight and the stitching should be even when sewing the lap part.

6. After stitching, the geotextile should be checked whether it is laid flat and whether there are defects.

7. If there are any irregularities, they should be repaired in time.

Geotextile installation and construction precautions.

1. Geotextile can only be cut with a geotextile knife, such as cutting in the field, special protection measures shall be taken for other materials to prevent unnecessary damage to the geotextile due to cutting.

2. While laying geotextile, all necessary measures must be taken to prevent damage to the following layer of material.

3. While laying the geotextile, care must be taken not to allow substances such as stones, large amounts of dust, or moisture that could damage the geotextile, that could block drains or filters, or could make the ensuing connections difficult, to enter the geotextile or the underside of the geotextile.

4. Visual inspection of all geotextile surfaces at the end of the installation to determine that all damage is marked and repaired and that the laying surface is free of foreign materials that could cause damage, such as broken needles and other foreign objects.

5. The connection of the geotextile must follow the following regulations: Under normal circumstances, there must be no horizontal connection on the slope (the connection shall be along the contour of the slope without intersecting with it), except for the place of repair.

6. If stitching is used, the stitching line must be made of the same or more material than the geotextile, and the stitching line must be made of chemical UV-proof material. The stitching line and geotextile should have an obvious color difference to facilitate inspection.

7. Special attention should be paid to the seams during installation to ensure that no soil or gravel from the gravel cover enters the middle of the geotextile.
